They sell the fuel pump £100 or a fuel pump repair kit! £23
O and its a pain in the arse to get out, fuel tank off, carbs off, air filter off, plastic covers over the ignition barrel off, un plug front cylinder HT lead, un do bolts holding the fuel pump cradle, then slide it out through the top of the frame. Jobs a bobby!
